Taxpayer funding has partial overlap with slave labor and with theft. It takes people’s wealth by force, regardless of whether they agree or disagree with what the government is using the wealth for. Therefore taxpayer funding should be used highly conservatively – in limited ways when we really can't figure out an alternative. It should be a last resort, not something used casually. There are worse things one can say about taxes. This is a limited, modest statement that all reasonable people ought to be able to agree with it. But instead we live in a nightmare world where most people seem to think it’s good to use $200,000,000 of taxes on a project just because they expect the value from the project – after successful completion within the budget – to be $220,000,000, or because the project promotes some value they care deeply about but find it difficult to voluntarily raise $200,000,000 for.
